It's been a while since we've heard new music fromKelly Clarkson and it's been since 2009 since she released a studio album! However, all that is finally changing, as Kelly has finally put out her new single Mr. Know It All, which she released the video for today!

The song is the debut single off Clarkson's FIFTH studio album Stronger, which hits stores on October 24. The album was actually set to release much earlier than this October date, but Clarkson announced back in March that although the album was complete, she had to wait until the fall to release it. Either way, new music is here now, so check out the video!:

Clarkson debutes a number of different looks during the video, which features a wall of negative headlines that have previously been released about her career. The singer spoke with MTV News about how the video represents many different sides of her. "I think there's that free-spirit side of me, and then there's that fiesty performer in me," she explained. "Then there's the funny side of me. I mean, obviously you have to be funny to have a big giant wall of doubt with actual headlines of your life on the wall. It's a little fun, a little fiesty."

She also opened up about the choice for making Mr. Know it All the first single, saying, "It was actually the last song we recorded and we had already finished it up. The song came out of nowhere, and luckily it did, because everyone fell in love with it!"
